LED Engin has more than doubled the light output of its previous version’s RGBW LED emitters without increasing the emitter size, with the launch of a 4-die, high current, RGBW flat lens LED emitter. This sets a new standard for flux density in stage, entertainment and architectural lighting.
The reason that the tiny emitter LZ4-04MDPB delivers such a high light output is that each individually addressable green, blue and white die can be driven at up to 3 amps and the red die up to 2.5 amps from the same 2.15mm x 2.15mm light emitting surface as its predecessor.
The emitter’s output ranges with everything from tungsten-effect white lighting to a full spectrum of brilliant colour in fixtures such as moving heads with zoom optics, directional effect lighting and wall washes.
Packed in a 7x7mm footprint, the emitter dissipates up to 40 watts of power through its thinner, 4-channel, multilayer ceramic substrate with a low thermal resistance of 0.9 °C/W. Good heat dissipation allows each die to be driven to a higher current without compromising reliability or operating life.
With a smaller substrate and thinner flat glass lens compared to the previous version, tightly controlled beam widths down to four degrees are possible. Secondary optics can therefore be positioned closer to the surface, to increase coupling efficiency to deliver powerful, punchy illumination from fixtures.
LED Engin CEO, David Tahmassebi, said, “Once again, we’ve advanced our proprietary technologies to deliver exactly what customers in these demanding lighting applications have asked us for: ever higher light output without increasing the emitter size. Most importantly, we’ve done so in a way that ensures sustained performance and long-term reliability.”
LZ4-04MDPB emitters are available now from LED Engin and its distributors.
